IMPROVEMENT IN SMOKING-TUBES.

Specification forming part of Letters Patent No. 185,284, dated Decemberl2, 1876; application tiled t July 15, 1ste.

To all whom t may concern:

Be it known that I, MARTIN BOURKE, of Mineral Ridge, in the county ofTrumbull and State of Ohio, have invented a new and ImA provedTobacco-Pipe 5 and I do hereby declare the following to be a full,clear, and exact description ot' the same.

In the drawing accompanying and forming part of this specification,Figure l represents a side view of my invention. Fig. 2 is alongitudinal section of the same in the line 00 w of Fig. l. Fig. 3 is across-section on line y g/ of' Fig. l.

This device is an improvement-in the class of cigar-pipes, or pipeshaving the form and general appearance of a cigar, and designed forsmoking line-cut tobacco. y

The improvement relatesparticularly to the provision ot' a detachableinner` tube or cylinder for holding the tobacco, and to the form oithein'ner end of the mouthpiece, against which the tube abuts; also, to aspring attached to a detachable end piece or plug, and whose 'functionis to hold the tobacco-tube against the mouth-piece, all as hereinaftermore fully described.

In the accompanying drawing, the body 0f the cigar-pipe is showncomposed of a tube or cylinder, A, havinga mouth-piece, B, andperforated plug O' attached to its respective ends by means otbayonet-fastenings, so that they may be readily detached, as occasionrequires. The tube D is made ot such size as adapts it to t the interiorot' tube A, and is made about halt' the length ot' the latter. It isuted or grcoved exteriorly to lessen the area of the surface of contactbetween it and the inclosing-tube A, so that it will not readily Aspiral spring, E, is attached to the inner end of plug O, which actsagainst the contiguous end of the tobacco-tube D, and thus causes theopposite end of the same to press tightly against the inner end of themouth-piece B. This is necessary to prevent air forcing its way to thelatter between the tubes A and D, in place of passing entirely throughthe tobacco-tube, as required, to support combustion. The inner endofthe mouth-piece is bored out to form a concavity, a, so that the draftor suction may not be restricted to the center of the body of thetobacco contained in the tube D, but applied to or over the entire endof the saine.

When it is desired to prepare the pipe for smoking, the mouth-piece B isfirst detached and the tube D removed, filled, lighted, and replaced,and the mouthpiece again attached. It is, however, practicable to tilland light the pipe by detaching plug C.

I do not restrict myself to the materials of which the several parts ofmy improved pipe may be composed, but I prefer to make the tobacco-tubeof clay or mcersehaum-chips, in

order that it may have the requisite lightness and lire-resistingquality.

The tubes'A and D may be conveniently and quickly cleaned with a swab,andthe pipe thus kept in proper condition.

As shown in the drawing, the tube or cylinder A is inserted in a woodentube or case, having a swell at the middle to give it the form andappearance of a cigar.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. In a tobacco-pipe, the combination, with the cylinder A, of thedetachable tube D, the mouth-piece B, spring E, and plug O, havingconcavity a., substantially as shown and described, t'orthe purposespecified.

2. In a tobacco-pipe, the detachable tube D, tluted or groovedexteriorly, in combination with the cylinder A, as shown and described.
